However, the existing equipment cannot be effectively lubricated during long-term movement, which may lead to wear and jamming of the moving parts of the equipment, thereby affecting the flexibility and stability of the equipment. This problem of insufficient lubrication may be due to defects in the equipment design or deficiencies in the lubrication system. Content of the Utility Model

[0029] Please refer to Figures 1-5, A weld flaw detection device, including a support frame 1, the support frame 1 is installed on an external device, a lubrication mechanism is provided on the support frame 1, the lubrication mechanism includes a lead screw 2, a transverse plate 3, a moving mechanism, an oil outlet sleeve 4, a one-way disk 5, a semi-circular sleeve 6, a top ball 7 and an adjustment mechanism. The lead screw 2 is rotatably connected to the support frame 1, the lead screw 2 is threadedly connected to the transverse plate 3, the moving mechanism is cooperatively connected to the transverse plate 3 and the oil outlet sleeve 4, the one-way disk 5 is attached to the inside of the oil outlet sleeve 4, the semi-circular sleeve 6 is installed on the one-way disk 5, a top ball 7 is rotatably installed inside the semi-circular sleeve 6, a plurality of internal grooves 8 are formed on the inner wall of the semi-circular sleeve 6, the internal grooves 8 communicate with the semi-circular sleeve 6, and the adjustment mechanism is installed on the oil outlet sleeve 4. The adjustment mechanism includes a rotating rod 9 and a threaded sleeve 10. The rotating rod 9 is rotatably connected to the inside of the oil outlet sleeve 4, the threaded sleeve 10 is threadedly connected to the inside of the oil outlet sleeve 4, the rotating rod 9 is installed on the threaded sleeve 10, an insertion rod 11 is provided on the one-way disk 5, the insertion rod 11 is slidably connected to the threaded sleeve 10, a spring 12 is sleeved on the insertion rod 11, and both ends of the spring 12 respectively abut against the threaded sleeve 10 and the one-way disk 5. An oil inlet pipe 13 is provided on the side wall of the oil outlet sleeve 4, and the oil inlet pipe 13 is connected to an external oil supply device. A plurality of annular grooves 14 are equidistantly formed on the lead screw 2, and the top ball 7 abuts against the annular grooves 14.

[0030] In this embodiment, when lubrication is not required to stop, at this time, the top ball 7 abuts against the annular groove 14, and the one-way disk 5 is attached to the oil outlet sleeve 4. Therefore, when in a sealed state, when the lead screw 2 rotates, the top ball 7 disengages from the annular groove 14, and then the top ball 7 abuts against the side wall of the lead screw 2. Therefore, the seal between the one-way disk 5 and the oil outlet sleeve 4 will be released, and then the lubricating oil flows into the semi-circular sleeve 6 through the oil outlet sleeve 4, and then flows into the top ball 7 through the internal groove 8, thus completing the lubrication process. When it is necessary to adjust the normal sealing pressure, by driving the rotation of the turntable, the threaded sleeve 10 can be rotated. Since the threaded sleeve 10 is threadedly connected to the inside of the oil outlet sleeve 4, the spring 12 can be compressed, thereby changing the sealing force, and then the adjustment process is completed.

[0031] Please refer to Figure 1 , As an implementation manner of the moving mechanism: The moving mechanism includes a slide rail 15, a motor 16 and a belt 17. The slide rail is installed on the support frame 1, the transverse plate 3 is slidably connected to the slide rail, the motor 16 is installed on the support frame 1, the extending end of the motor 16 meshes with the belt 17, the belt 17 meshes with the lead screw 2, and cylinders 18 are respectively provided at both ends of the transverse plate 3, and detection heads 19 are respectively provided at the extending ends of the cylinders 18.

[0032] More specifically, when flaw detection is required, first, the motor 16 drives the rotation of the lead screw 2. Since the lead screw 2 is threadedly connected to the transverse plate 3, it can drive the cylinder 18 and the detection head 19 to move. Then, by the up and down movement of the cylinder 18, the detection head 19 can be moved to the corresponding position, and then the weld seam is detected, thus completing the flaw detection process.

[0033] In summary, when the overall device is in use or operation: when lubrication is not required and stopped, at this time, the top ball 7 abuts against the annular groove 14, and the one-way disk 5 fits against the oil outlet sleeve 4. Therefore, when in a sealed state, when the lead screw 2 rotates, the top ball 7 disengages from the annular groove 14, and then the top ball 7 abuts against the side wall of the lead screw 2. Thus, the seal between the one-way disk 5 and the oil outlet sleeve 4 will be released, and then the lubricating oil flows through the oil outlet sleeve 4 onto the semi-circular sleeve 6, and then through the internal groove 8 into the top ball 7, thus completing the lubrication process. When it is necessary to adjust the pressure of the normal seal, by driving the rotation of the turntable, the threaded sleeve 10 rotates. Since the threaded sleeve 10 is threadedly connected inside the oil outlet sleeve 4, the spring 12 can be compressed, thereby changing the sealing force, and thus completing the adjustment process. When flaw detection is required, first, the motor 16 drives the rotation of the lead screw 2. Since the lead screw 2 is threadedly connected to the transverse plate 3, it can drive the cylinder 18 and the detection head 19 to move. Then, by the up and down movement of the cylinder 18, the detection head 19 can be moved to the corresponding position, and then the weld seam is detected, thus completing the flaw detection process.

[0034] In all the above-mentioned solutions, for the connection between two components, welding, the cooperation of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above involving fixed connection, welding is preferably considered.
